Title: Set of structural elements, composed of a concrete frame for receiving a cellar window, of a light-shaft lower part to be connected thereto and of connecting means, and process or apparatus for producing a concrete frame for such a set of structural elements
Inventor: KUENSTLER WILHELM
IPC: E04F17/06
Filed: 1981-04-08
Abstract: The invention relates to a set of structural elements, composed of a concrete frame for receiving a cellar window, of a light-shaft lower part to be connected thereto and of associated connecting means, and a process or an apparatus for producing concrete frames for such a set of structural elements. The intention is for it to be possible to produce said set of structural elements in a simple and reliable manner, in particular in terms of the concrete frame, with accurately fixed position of the connecting means, and for said set of structural elements to allow simple assembly. This is essentially achieved in that, in the concrete frame, holes for receiving the connection means start from the end-side outer surface of the concrete frame and extend only over a part thereof, preferably approximately half the depth of the concrete frame, and, at the inner end, pass into a groove or slot which is open towards the interior of the frame and intended for receiving an anchoring part. A process or an apparatus for producing a concrete frame for such a set of structural elements is distinguished, in particular, in that a mould lower part bears radial moulding elements which are directed towards the outer casing of the mould and are intended for forming the grooves in the concrete frame, axial rounds or flats for forming the holes in the concrete frame being connected to said moulding elements, or in that a press-on frame of the mould has end-side rounds or flats for forming the holes in the end-side outer surface of the concrete frame and radially adjustable slides for forming the slots in the concrete frame are arranged in the mould lower part. <IMAGE>

Patent DE-3114946-A1 (DE)
Title: Shut-off and control valve
Inventor: NEMETZ JOSEF
IPC: F16K3/02
Filed: 1981-04-13
Abstract: In the case of shut-off and control valves which are used to shut off or to control liquid or gaseous media flowing through pipelines, there is inserted into the housing, which has an entry opening and an exit opening, a shut-off element which can be a cylindrical or frustoconical plug or a ball or a valve plate. The shut-off element has an opening or cutout which, when the valve is opened, connects the entry opening to the exit opening and, when the valve is closed, shuts the two openings off from one another. Between shut-off element and inner wall of the housing is a gap in which a seal surrounding the entry opening and/or exit opening is inserted. The material used for the seal is one which has inherent elasticity and can be squeezed into the gap between housing and plug so that it presses both against the inner wall of the housing and also against the circumferential surface of the shut-off element. These shut-off and control valves can generally be used only at low temperatures and/or at low pressures, or are too stiff. These disadvantages are eliminated by virtue of the fact that the seal, inserted into the gap, bears against the inner wall of the housing and has a lip which runs around the entry and exit opening, is angled obliquely inwards, with the shut-off and control valve open surrounds the passage in the shut-off element and bears resiliently against the shut-off element, and the seal is composed of elastic material.

Title: Circuit for selectively switching off a defective power supply device
Inventor: MAEDER ROLF
IPC: H02J9/06
Filed: 1981-06-29
Abstract: In the case of an interconnected system formed from two power supply devices (I, II) it is intended that the respectively defective power supply device be switched off (cut off) in the event of a defect. A defect signalling device (M) is provided in order to monitor the correct operating condition of the interconnected system and for detecting defects. Switching means (M1) of this defect signalling device initially switch the power supply device (I) off in the event of a defect being detected and - if the defect is then still present - subsequently switch off the other power supply device (II). At the same time, that power supply device (I) which was switched off first is switched on (connected) again. The circuit according to the invention for this purpose requires two switching contactors and an RC element as well as the defect signalling device. <IMAGE>

Title: Electronic counter
Inventor: MERKLE PAUL
IPC: H03K23/50
Filed: 1981-07-17
Abstract: In this electronic modulo-10 counter, the resetting of the relevant flip flop is also preselected by the own counting output as in the electronic counter according to the main patent application (P 3047169.3). In contrast to the electronic modulo-10 counter according to the main patent application, each decade in the present modulo-10 counter only consists of five flip flops, four of which are combined with delay circuits. Two flip flops of these are change-over flip flops; the remaining three flip flops of each decade are the counting flip flops. In this electronic counter, one decade cycle thus consists of three passes. <IMAGE>

Patent DE-3132900-A1 (DE)
Title: Device for locking and unlocking mould plates of an injection mould
IPC: B29C45/26
Filed: 1981-08-20
Abstract: The invention relates to a device for locking and unlocking mould plates of an injection mould, which can be moved together and apart in two parting planes. The device has a control strip attached to a first mould plate, a coupling strip which is opposite the control strip and is attached to a third mould plate, and coupling parts which are guided in a second mould plate arranged between the first and third mould plates, so as to be tensile-resistant and compression-resistant in the plate-movement direction and so as to be movable transversely to the plate-movement direction. The problem in the case of devices of the aforementioned kind consists in the fact that flexural moments occur on the control strips or coupling strips, which flexural moments are transferred to the guide of the mould plates. The flexural moments are eliminated in that, at its opposing longitudinal sides (51), the coupling strip (5) is designed so as to be mirror-symmetrical with respect to the longitudinal central axis of the device, in that one of two symmetrical control strips (4) is provided at a distance from each longitudinal side of the coupling strip and in that a coupling part (6) is provided between each control strip and the coupling strip. Exemplary applications are so-called sprue-puller moulds, in which the sprue is detached from the moulding during the demoulding and the moulding emerges from the injection mould from the main parting plane, and the sprue emerges from the injection mould from a further parting plane. Similar movement sequences can be controlled in the case of stripper plates and ejector plates of injection moulds. <IMAGE>

Title: Circuit arrangement for generating a pulse voltage having a sawtooth-shaped mean value
Inventor: SCHOERNER JOCHEN DR ING
IPC: H03K5/156
Filed: 1981-09-18
Abstract: The invention relates to a circuit arrangement for generating a pulse-width-modulated voltage Up having a mean value varying in the form of a sawtooth. To create such a circuit which is distinguished by much less circuit complexity than the known circuit arrangements and, nevertheless, is at least equivalent to the latter in functional respects, a step generator for generating a current IH having at least approximately hyperboloid amplitude characteristics within the individual sawtooth intervals (Ts) is provided. Furthermore, an integrator (17-19) fed with the current (IH) and integrating this current, a device (20-22) for resetting the integrator (17-19) to zero a number of times within each sawtooth interval (Ts) and a comparator circuit (23, 24, 26), which compares the output signal (Ul) of the integrator (17-19) with a direct voltage (UV) in such a manner that the output signal (Up) of the comparator (23, 24, 26) represents the pulse-width-modulated signal with sawtooth-shaped mean value, are provided. <IMAGE>
Patent DE-3137930-A1 (DE)
Title: Chopping machine
Inventor: WIRTH AXEL
IPC: B02C13/286
Filed: 1981-09-24
Abstract: In a chopping machine for comminuting waste, in particular for comminuting waste wood and paper, which is provided with a rotating rotor to which the material to be comminuted is fed via a charging funnel which is inclined outwards in a plane perpendicular to the axis of the rotor, the intention is to prevent the portions of material which are thrown back by the rotor from emerging from the charging opening of the funnel. This object is achieved according to the invention in that on the inside of at least one of the inclined funnel walls at least one impact wall which extends upwards approximately vertically on the wall, is directed towards the discharge direction of the material and engages over part of the cross-section of the funnel is arranged, which impact wall is supported by a supporting wall which is directed towards the charging opening and is located at an incline. With this arrangement, it is ensured that the material which is thrown back by the rotor strikes the impact wall and, at the said wall, is deflected back to the rotor so that even when the charging opening is open it cannot emerge from the said opening.
